Reduce kidney stone risk

What this outcome means

Kidney stone risk is how likely your body is to form the hard mineral deposits that can lodge in the urinary tract. On DoseRank it maps to a defined health outcome built from human studies on stone recurrence rates, urinary mineral levels, and crystal formation markers – data sourced from open sources and specialized resources. DoseRank is not medical advice.

Who it's for

Repeat stone formersPeople who have passed more than one stone before.

Concentrated urineLow fluid intake that leaves minerals prone to crystallizing.

Family historyA genetic tendency toward stones running through the family.

Stack buildersAlready taking supplements such as Calcium Citrate and want the dose right.
